In my opinion, a good guesser may not succeed in gambling. This is because gambling and prediction are two different things. Gambling requires more than just a guest work to record a win. Any gambler who rely on guessing will continue to lose heavily because such a gambler will not want to look into statistics which is vital for making a good prediction.
Besides that, in predicting a match, a person needs the ability to gather more information to analyze the match and find a team that has a chance of winning. With good analytical skills, he may be able to find his team, which will cause him to lose more often because in placing bets, he will rely more on his guesses rather than using his analysis. But if he wants to learn how to analyze a match and find a place to get useful information, he can become a gambler who gambles in sports betting. And he can also predict which team can win against other teams so he can win the bet.
